Kayan Miqewa:  

Lokacin da buƙatun abokin ciniki don kayan ba su da wahala sosai, kuma maimaita gwaje-gwajen ƙira sun kasa cika buƙatun, zaku iya canzawa zuwa kayan da ke da kyawawan kaddarorin tensile kuma sake gwadawa. Kyakkyawan abu shine rabin nasara. Don mikewa, ba dole ba ne a yi watsi da shi. Cold-birgima bakin ciki zanen gado don zane musamman sun hada da 08Al, 08, 08F, 10, 15, da 20 karfe. Mafi girman adadin shine karfe 08, wanda aka raba shi zuwa karfe mai kauri da kuma kashe karfe. Ƙarfe na rimmed yana da ƙananan farashi kuma yana da inganci mai kyau. Warewa ya fi tsanani kuma yana da halin "tsufa". Bai dace da sassan da ke buƙatar babban aikin hatimi da buƙatun bayyanar ba. Karfe da aka kashe ya fi kyau, tare da aiki iri ɗaya amma farashi mafi girma. Alamar wakiltar ita ce aluminum kashe karfe 08Al. Karfe na waje ya yi amfani da SPCC-SD na Jafananci mai zurfin zane mai zurfi, kuma kaddarorin nasa sun fi 08Al. Lokacin da buƙatun abokin ciniki don kayan ba su da wahala sosai, kuma maimaita gwaje-gwajen ƙira sun kasa cika buƙatun, za su iya canzawa zuwa wani abu kuma su sake gwadawa.

Lokacin da ake yin zane mai zurfi, ɓangarorin biyu na mutu da mariƙin ba su isa ƙasa ba, musamman lokacin zana faranti na baƙin ƙarfe da faranti na aluminium, ƙyallen zane na iya faruwa, wanda zai iya haifar da karaya a cikin mawuyacin hali.

Ƙayyadaddun Girman Blank:  

Ƙarin wrinkles da ƙananan fasa sune ka'idar mu. Ya kamata ƙirar sakawa mara kyau ta zama daidai. Diamita mara kyau na ɓangaren zanen jiki mai jujjuya tare da sifa mai sauƙi ba zai zama bakin ciki ba. Kodayake kaurin kayan yana canzawa, yana da kama da ainihin kauri. Ana iya ƙididdige kusanci bisa ka'idar cewa yanki na blank da yanki na ɓangaren da aka shimfiɗa (idan dole ne a ƙara trimming) daidai suke. Duk da haka, siffar da tsari na sassa da aka shimfiɗa sau da yawa suna da rikitarwa, kuma wani lokacin suna buƙatar raguwa da shimfiɗa. Kodayake akwai software mai girma uku masu yawa waɗanda zasu iya ƙididdige kayan da aka buɗe, daidaiton sa ba zai iya cika buƙatun 100%. 

Magani: samfurin. Dole ne samfur ya bi ta matakai da yawa, kuma tsari na farko gabaɗaya tsari ne mara tushe. Da farko, wajibi ne don aiwatar da lissafin abubuwan da aka buɗe, kuma a sami cikakkiyar fahimta game da sifa da girman blanking, don sanin girman girman mutuwar blanking. Kar a aiwatar da madaidaicin madaidaicin ƙulli da madaidaicin ƙulli na gyaggyarawa bayan an gama ƙirar ƙirar. Da farko a yi amfani da yankan waya don sarrafa babur (lokacin da babur ya fi girma, ana iya niƙa shi da injin niƙa sannan a danne shi). Bayan gwaje-gwajen da aka maimaita a cikin tsarin miƙewa na gaba, an ƙayyade girman da ba komai a ƙarshe, sa'an nan kuma ana sarrafa nau'in convex da concave molds na blanking die. 

Experience 2: Juya tsarin, da farko gwada zanen mutu, sannan aiwatar da girman gefen blanking na blank, wanda shine rabin ƙoƙarin.
